Claims. (Cl. 68-189) This invention relates to apparatus for the treatment of hollow yarn packages and'more particularly to apparatus for Washing packages of viscose rayon.

An obje ct is to provide novel and improved apparatus for sealing the top of a stack ofsuch yarn packages.

Another object is to provide a sealing means the sealing pressure of which is proportional to the fluid pressure of the washing liquid or the like within the stack.

Another object is to provide a sealing means of the above type in which the sealing pressure is maintained only slightly above the fiuid pressure within the stack.

Another object is to provide a sealing means of the above type which permits the yarn packages to expand or contract during treatment without substantial change in sealing pressure thereon.

A feature of the apparatus according to the invention is the provision of a sealing lid which is automatically lifted oif the uppermost package of the stack at the termination of the treatment when the fluid pressure is removed from within the stack. The lid lifts through a considerable distance so as to provide clearance to facilitate the removal and exchange of the packages.

In accordance with the invention the separate hollow packages of yarn are built up into a stack having no internal sleeve. The stack is mounted on a perforated base plate and a lid is used which is secured to an elastic expansion member so that internal pressure within the expansion member presses the lid against the top of the stack. The hollow interior of the expansion member is connected to the hollow interior of the stack so that the sealing pressure of the lid varies with the pressure of the fluid in the stack.

The efi'ective mean diameter of the expansion member is preferably greater than the effective mean diameter of the stack of packages, whereby the lid is constantly pressed onto the stack as a result of the pressure differential.

In a modification, the hollow space of the expansion member is subjected to a pressure derived from the exterior through a separate conduit, said pressure being related to the pressure within the stack.

In the accompanying drawing which illustrates certain embodiments of the invention:

Fig. 1 is a partial vertical section of a stack ofyarn packages illustrating one embodiment of the invention;

Fig. 2 is a similar section illustrating another embodiment of the invention; and

Fig. 3 is a diagrammatical view, partly in section showing a complete fluid-treatment installation in which the sealing arrangement of Fig. 1 is employed.

In Fig. 1 the uppermost package 1 of a stack of pack ages is covered by a movable lid 2 which is rigidly connected (as by welding) to an elastically deformable member 3.

The stack is mounted between two supporting posts 4 and 5 and is built up in the customary rings 6 between Hce 2 the separate packages. One of these rings 6 is visible beneath the package 1.

The expansion member 3 is mounted on the upper ends of the posts 4 and 5. A ring 7, the internal diameter of which is the determining factor for the efiective diameter of the expansion member, is manifest between the said expansion member and the tops of the posts 4 and 5.

A bell-shaped casing 9 is fitted over the expansion member 3. The said bell-shaped casing has a connection it) leading to a source of fluid pressure, and an axial guide in the form of a rod 11. The movable lid 2 has an axial bore 12 which slides on the guide rod 11.

In Fig. 2, which shows another embodiment and has the same reference characters as Fig. 1 for identical parts, the, expansion member 3a of Fig. 2 is constructed as a bellows.

For an explanation of the method of operation, Fig. 3 shows diagrammatically an installation for the treatment of yarn packages. The hollow space formed by the bellshaped casing 9 and the expansion member 3 is connected through connection 10 and pipe 13 to conduit 14 which leads to a source of pressure liquid (not shown). A pressure chamber 15 is interposed in the pipe 13. The conduit 14' also supplies pressure liquid to the interior of the stack of yarn packages.

If liquid is now forced through the stack of packages 1 through the supply conduit 14, the said liquid also rises through the pipe 13 into the pressure chamber 15. The resultant compression of the air within the pressure chamber 15' pressurizes the hollow space within the expansion member 3 and below the bell-shaped casing 9, to force the movable lid 2 downwardly against the top of the stack of yarn packages 1. Since the eiiective diameter of the expansion member is somewhat greater than the effective diameter of the space within the stack of packages, the pressure exerted on the movable lid from above is sufficient to hold thelid in sealing contact with the top of the stack.

If, at the termination of the treatment, the treatment liquid is drained off, for example by means of a cock 16, the level of liquid in the pressure chamber 15 also fails. In the air space above the liquid level in the pressure chamber a negative pressure is therefore set up whereby the movable lid 2 is raised and the stack of packages may be dismantled.

The expansion member 3 in either of the two embodiments described can be made of metal, synthetic material or, for example, reinforced soft rubber.

Obviously, various stacks having different liquid connections to the same pressure conduit can be mounted together on a common base plate. The latter can stand in a draining channel so that the treatment liquid may be ages by means of hot gases.

l claim: 1. Apparatus for the fluid treatment of a hollow package of textile yarn having an axial passage therein, comprising a horizontal support for carrying said package and having a port for communicating with said axial passage,

a conduit connected to said port to supply treating fluid to said passage, resilient sealing means comprising a rigid sealing wall having a diameter greater than that of such passage, means supporting said sealing wall above and in line with said port for contacting the top of said package and an expansible side wall extending upwardly from said sealing wall and forming therewith a closed chamber, said side wall being extensible in response to fluid pressure within said chamber, and means connecting said conduit to apply the pressure of the treating fluid to said chamber for expanding said side wall for holding said sealing wall in sealing engagement with the top of said package.

2. Apparatus for the fluid treatment of hollow yarn packages arranged in a stack having an axial passage therein for treating fluid, comprising a horizontal support for carrying said stack, said support having a bore for communicating with one end of said axial passage, a rigid closure wall having a diameter greater than that of sai passage, means supporting said closure wall above an in line with said bore for closing the other end of sai passage, a resilient expansible wall extending up wardly from said first wall and forming therewith a closed pressure chamber, means for supplying treating fluid through said bore to said axial passage, and means applying the pressure of said fluid to said chamber for expanding said expansible wall for holding said closure wall in sealing engagement with the top of said stack and clos ing said axial passage.

3. Apparatus for the fluid treatment of hollow yarn packages arranged in a stack having an axial passage therein for treating fluid, comprising a horizontal support for carrying said stack, said support having a bore for communicating with one end of said axial passage, a rigid closure wall having a diameter greater than that of said passage, means supporting said closure wall above and in line with said bore for closing the other end of said passage, a resilient expansible Wall extending upwardly from said first wall and forming therewith a closed pressure chamber, means supplying treating fluid through said bore to said axial passage, a pressure system connected to apply pressure to said chamber, and means responsive to the pressure of said treating fluid to exert pressure on said pressure system for expanding said expansible wall for holding said closure wall in sealing contact with the top of said stack for closing said axial passage.
